INVENTOR WITNESSES wardly exten'ding portion of saidoonduit 31, being conveniently controlled by the valve 40. The fan 36, is connectedtoa'be driven through suitable connection," by the motor 5,41. 1 The beard 25, is provided with'the rack "42, whereby itj'inay'bevlaterally shifted by rotation ofthe handwheelii, disposed con-- ven 'enttothaoperator and 'providedwith a shaft 44:, having the 'gear45, in'tOQthed enlegagement with said rack. In order to inf sure-."the sync ronous movement of the conduit 31, ,wi 11 the suction funnels .28, threadedfs'haft's 46 and 47, are journaledin disposednear' the hood 48, of said 15- car,;qan d are respectively provided with miter' gears- 5fi and 51; Thegear 50, is in with miter-gears 52 onithe shaft 53,

which 'is provided with a gear 55, in mesh w'ith the gear 56,011 the shaft d4, and-said ZQJmiterL-gear 50in also in mesh with'the miter gear 58,1 whose shaft provided .with the miter" gear 59,iin; mesh'with. themiter gear The threaded j; shaft s- 46 and 47, are in fl readed engagement i with the. cross heads -131) 5 and '61,. which respectively I extend through the slot 62, in the front vestibule and through; the j slot 63, in said hood 48, said cross-heads are arranged to slide in guides64'and-65 respectively and embracethe Econveyer "conduit 31', as. best shown in is best-fshowngin Fig. 6,- the conveyor :ondnit is provided. with the cylindrical pivotaljconnection whichcomprises the sta-. as tionaryp'o'rtion ofsaid cgnduit 31, having the ,semicyiindrical; end 68, fitted over the scmicylindricali land 69, of the oscillatory portion, andfsaid oscillatory portion has its end telescopically fitted over the reduced 9 '70; of-the'latei'ally movable portion.

The oscillatoryportion isconvenie'ntly supportedby the shoe 72, mounted to slide in the guide plate 73. i v

i The ,beam' 25, carrie'sfthe stationary brushes 75, which are oppositely inclined as best shownin Fig. 5, and tend to throw the surface refuse of thestreet, especially that which-is adjacentto the curb, toward the center; The rotary brush 78, ,has its shaft 79 ,journaled in bearings in the free ends 7 o f'the links-80, which arepivoted to said beam 25, andc'arried therewith The brush .shaft 79, is provided with pulleys connected by' belts 82,: with pulleys on the countershaft 5, 83, which is journaled in suitable bearing;

7. 84, on said beani25. ihe counter-shaft 83, is provided withv the driving pulley 85, which has the key 86, engaged with thekey- .way 88, extending throughout its length,

and said pulley 85, is prevented from moving laterally with said shaft by the bearing hrackets' 87, depending from the motor cas-' ing 90. The pulley 85, is connected by the driving beltQI, with the electric motor 92, 5 which is inclosed within the meter casing ceases 90, and may be electrically connected with the trolley wire 95, through the trolley and its supporting pole 9 6. l

It may be observed that-the surface refuse of the street is loosened by the action of the brushes and that when thus agitated is drawninto the mouth of the suction funnels by the inrush of air caused by the partial vacuum created by blades 37 ofitherotary blower fan 36. Furthermore it may be notedthat by the lateral adjustment of the mechanism above described, the entire width of the street surface may be cleaned while the vehicle traverses the center'thereof.

It is not desired to limit this invention to the precise details of construction and ar- 'conveyer conduit v comprising a stationary portion connected wlth said receptacle, and amovable portion connected with the funnel,

and having their adjacent ends pivotally connected to permit the lateral oscillation of said movable portion. 2. In a vacuum cleaner the combination with a' vehicle comprising a receptacle; of a vacuum suction funnel; a beam supporting said'funneli mounted for lateral rec1proca-.

tion and having a rack a gear arranged to engage said rack to shift said beam; a conveyer conduit compr sing astatlonary portion connected with said receptacleand a movable portion connected with said funnel,

said portions having adjacent semicircular ends interlocked to form an air tight pivotal connection, and said movable portion having a telescopic region to permit its elongation.

3. In a vacuum cleaner, the combination with a car,.'o f a beam movable transversely thereto. a suction funnel carried by said beam; a receptacle; a vacuum conduit, comprising a stationary portion and a movable portion pivotally connected therewith, connecting said funnel with said receptacle;

means to reciprocate said beam, and means connectedtherewith arranged to reciprocate said conduit in accordance therewith.

4. in a vacuum cleaner, the combination with a car, of a receptacle, a beam movable transverse to the movement of said car; a-

conduit having a pivotal connection and a telescopicportion; a suction funnel, carried by said beam and connected with said receptacle by said conduit; and means to engage laterally; a cross-head slidable in suitable said beam and said conduit to shift them guide-ways and connected with said conduit, 10 laterally. to shift it in accordance with the movement 5. In a vacuum cleaner, the combination of said funnel.

with a car, of a receptacle; a suction funnel, JOHN FRANCIS SHEA.
